Effects of single molecules on total and progressive sperm motility. Total and progressive motility of sperm suspensions (n = 5) treated with different concentrations of (A) zinc (1,10,100 μg/ml), (B) D-Asp (5,50,500,5000 μg/ml), or (C) CoQ10 (4,40,400 μg/ml), at 6 h of incubation. # Significant differences versus control at 0 h (P < 0.05). ** Significant differences versus control at 6 h (P < 0.01).
